I was never capable to get a perfect smooth picture from Freeview HD... I mean, the same kind of smoothness I get from DVB-S through FTA decoder...
I am talking about a very slight jittering, especially on vertical or horizontal scrolling text, or medium-speed pan. If the scrolling text has a fairly low or fairly high speed, or the panning is done at low or high speed, then the jittering is not obvious at all. This can be seen on both TV1/2 and Tv3. At a certain point I was thinking the pc tries to deinterlace the progressive signal (!!) as it was no other explanation for the jitter on Tv1/2;
I came accross with an explanation where it all came down to the diference between the 50Hz video signal and the fact that the panel sometimes expects 60Hz signal. But the video standard in NZ is 50Hz, right? If the screen needs to display @60Hz, the missing frames need to be covered by something, and the most common way this is achieved is by keeping every 12th frame on the screen for double the time. This is the explanation I found. Does it make sense?
In an ideal world, you would have to have a tv accepting the video standard available in that country, 50Hz video signal leaving the htpc, and a tv capable to display the native resolution @ 50Hz. And here I come and ask everyone to confirm if I am right or wrong in the way I understand how this works... because the Sony Bravia (at least the D series I have), DOES NOT ACCEPT 50HZ VIDEO SIGNAL !!!!!!!!!!!
Is this why I will NEVER get a perfect smooth picture?
Or maybe I did not get it right, and I am just talking nonsense?...
Here is the page from the User's manual refering to compatible video input from PC:
I used to have the card set to 1360x768 @60Hz, now it is 1360x768 @50Hz and I think is better, but the desktop needed to be resized (I had items outside the screen) and it does not look crisp anymore. But the video has a lower jittering level. I also tried other resolutions but not with good results.
The connection is: DVI -> DVI/HDMI cable -> HDMI into TV; Sound through separate stereo 3.5mm;
See this forum: http://www.xpmediacentre.com.au/community/home-theatre-audio-plasmas-lcds-projectors/15128-great-debate-50hz-vs-60hz.html
and I quote: "I am afraid that nothing can be done to skip refresh rate changes between different sources. Whenever you use source material in another timing (like PAL video in 60Hz out), you get frame rate conversion handled by the codec and the driver. Some codec/driver combinations may work better than others but no one can give perfect results. Only expensive professional frame rate converters used in the broadcasting industry can do that (like the ones for converting American programs for Europe or vice versa), but still you can tell the difference."
